讲述铝板表面滚涂工艺

铝板表面经脱脂、化学处理后，轧上优质涂层，干燥固化。辊涂板表面涂膜平整度高于喷涂板。颜色分为珠光和哑光，市场上最常见的是珠光。它的价格比喷雾高。辊涂板铝板的最大特点是色彩模拟度高；铝板辊涂工艺的质量和等级有很大的差别。除了所有的材料，它还与它的着色几次有关。例如，两涂两滚，即喷涂一次，烘烤一次，再喷涂烘烤一次，使颜色更加均匀光滑。一个好的辊涂板也非常昂贵，具有逼真的颜色和很强的耐用性。

进口氟碳辊涂也是辊涂的一种，即在铝板颜料中加入氟碳，使颜色更粘，使用寿命更长，耐酸碱和耐腐蚀。常用于建筑物的外部装饰（不怕风雨）。价格很高，是最高档次的涂布板。
表面处理工艺如下：
滚涂板上有面漆、底漆和背漆。背漆主要起到抗氧化作用，使用寿命更长。半成品加工成型卸料检验包装入库。
滚涂板表面均匀光滑，无漏涂、缩孔、划伤、脱落等明显缺陷。但表面存在气泡、凹坑、夹杂等微缺陷，属于正常现象。

After degreasing and chemical treatment, the surface of aluminum plate is rolled with high-quality coating, dried and solidified. The flatness of the coating film on the surface of the roll coating plate is higher than that of the spray coating plate. The color is divided into pearlescent and matte, and the most common one on the market is pearlescent. Its price is higher than spraying. The most important feature of roller coating board is the high degree of color simulation; There is a big difference between the quality and grade of roll coating process. In addition to all the materials, it is also related to its coloring several times. For example, two coating and two rolling, that is, spraying once, baking once, and then spraying and baking again, so that the color is more uniform and smooth. A good roll coating board is also very expensive, with realistic color and strong durability.

Imported fluorocarbon roll coating is also a kind of roll coating, that is, adding fluorocarbon in the pigment, making the color more adhesive, longer service life, acid and alkali resistance and corrosion resistance. It is often used in the external decoration of buildings (not afraid of wind and rain). The price is very high, and it is the highest grade of roll coating board.
The surface treatment process is as follows:
There are topcoat, primer and back paint on the roll coating board. The back paint mainly plays the role of anti-oxidation and makes its service life longer. Semi finished products - processing - molding - unloading and inspection - packaging and warehousing.
The surface of the roll coating plate is uniform and smooth, without obvious defects such as missed coating, shrinkage cavity, scratch and falling off. However, there are micro defects such as bubbles, pits and inclusions on the surface, which are normal phenomena.
